The Andean common bean AND 277 has the Co-1(4) and Phg-1 alleles that confer resistance to 21 eight races, respectively, of anthracnose (ANT) angular leaf spot (ALS) pathogens. Because its broad spectrum, is one main genes used in ANT breeding. Additionally, for ALS. In this study, we elucidate inheritance both pathogens using F(2) populations from × Rudá Ouro Negro crosses F(2:3) families cross. are susceptible all above races Co-segregation analysis revealed a single dominant gene confers...
Abstract Anthracnose caused by Colletotrichum lindemuthianum is one of the most critical diseases in common bean ( Phaseolus vulgaris L.). The characterization and localization pathogenic fungal races are essential for understanding pathogen population dynamics developing resistant cultivars. Here, we discussed relationship between diversity C. resistance genes against anthracnose disease. Indeed, several studies using a system 12 differential cultivars have been carried out since 1991 to...
ABSTRACT Novel sources of resistance are continuously needed to combat anthracnose disease in common bean ( Phaseolus vulgaris L.) caused by the hypervariable pathogen Colletotrichum lindemuthianum (Sacc. and Magnus) Briosi Cavara.

Abstract Anthracnose (ANT) is among the common bean fungal diseases responsible for significant yield and grain quality losses. Durable genetic resistance primary ANT control method due to pathogen's high variability. Genetic studies showed that chromosome Pv01 contains multiple disease genes, including loci Co‐1 ( 2 , 3 4 5 HY x ), Co‐AC Co‐Pa Co‐Perla Co‐w Co‐x CoPv01 CDRK . This work aimed to: (i) perform fine‐mapping of allele present in cultivar AND 277, using recombinant inbred lines...
